I have 4 five pound bags a compost and 23 jars BRF. Do u think i should go with my 1st setup which is puting 2 montubs each with 1 bag of compost and 3 jars in each. I was going to just birth the jars that i didn't use in the 2 tubs. Or should i do 4 montubs with 3 jars 5pound compost each. Im trying to get the bigggest yield possible. What do you guys think. oh yeah and when im using jars for casing do i dunk those too

That is an extremelly low spawn ratio. Most ppl for cubes do not go above 1:4 some 1:6. Commercial mushroom growers go as far as 100:1. I personally never go above 1:4

Do you mean you are going to break the cakes up and case them? If so you dont dunk.

BRF jars as spawn to bulk is a bit tricky. The thing is to birth the cakes at just the right time (my exp: 1-3 days after 100%, depending on strain.) so you get the mycelium at the peak of growth, but well before any pinning hormones are activated.
Then there is the issue of mixing the spawn into the new substrate. Breaking by hand is too damaging to brf cakes, so don't even think about it. Rye and all the other popular bulk grains break apart more easily and with less damage to the mycelium; another reason they are better as spawn. They spread out nice and easy as well, so you get an even layer each time. BRF cakes are discs, and without doing more damage you can't really change that.
Cutting them up just right is an art unto itself. Cut the pieces too big and you're using up spawn that won't have enough surface area to grow as fast as it could. Too small and it will be too weak to (you guessed it) grow as fast as it could.
1/2" slices works out best IME. Less trauma to the mycelium and a good ratio of mass/surface area. I use 1 part spawn to 1 part new sub. I like faster turn-overs since brf can take longer to colonize bulk subs.
It works ok, but brf is not the best bulk spawn. I do sealed casings on my cakes and pamper them and get better results than brf-bulks. I'd rather wait till I have invitro pins before birth/dunk and have 4-6 clean flushes yielding about an ounce every two weeks (10 cakes). BRF-spawn means having to wait an extra 2 weeks to colonize the sub, another 5-7 days or more to see pins, worrying about contaminates the whole time, having one awesome flush with an ok second flush and contaminates setting in at or before 3rd flush. Bah.
For all that work, I say put that energy into making bad-ass cakes and a superb FC.

PE is slower, so I'd leave them as cakes and fruit them in an SG. Wait till you get invitro pins, then dunk and roll in verm with a pinch of gypsum. Bake the verm or PC it before using it. Mold spores abound in the types of places that your bag has sat around in before you bought it.
I advise you to fruit everything as cakes, but if you're bound to try bulk, stay at one part spawn to one part new substrate.
I'm not sure what kit you're following, but colonizing grains and compost at the same time sounds wrong. Grains need to be sterilized, and manure/compost need to be pasteurized.
It's usually 100% colonized grains and THEN spawning to manure/compost/coir/whatever...
And by "usually", I mean that's how it's done.

im not using a kit anymore and yes i know how its done just didn't explain it well i bought a kit from homesteadbooks.com
but again not using a kit anymore i shot up 12 jars with Hawaiian and 6 with PE and 6 with B+ strain 1 Hawaiian went bad . My goal was to grow bulk so I bought 20 pounds of compost from Heady Poo off ebay.
again ? is can i use my jars to spawn the compost then grow off of there i m GOING to use what ever jars i dont use as spawn in my shotgun FC.
I wanna make 2 monotubs using PE and HAwaiian.
WHat should i do i have 6 PE and 5 HAwaiian fully colonized for the past 4 days. the rest are about 90% did tat batch week after the first 12 jars.
I already bought th Compost so i don't want to not use it. would be a waste.

1:4 the max. Most people from this site dont use a higher spawn ratio than that

i get that how many jars to the 5 pound not sue how to get a 1:4 ratio like i said I have use in the past a half pound bag of RYE berries as spawn in 3 pounds of compost. Thats is why i figure 3 jars in 5 pounds

See we are talking volume vs weight. It makes it harder to determine your ratio. You could take your cmpost and measure it out in cups then determine your ratio that way

i know its tricky but i dont see why it wouldn't work maybe 4 jars would be better but i dont know i think its should go fine. i know the jars ill birth as cakes will be but again no need to waste the compost

I know 6 cups of WBS is 1kg so I would think 5 lbs of compost would be about 15 cups or so. Id try 4 cakes to get a ratio close to 1:4

I always just estimate with the conversion 1pint=1pound. I know its not 100% at all times, and density of matter is everything. Its a good rough est.

You could always try something like this. Not too productive but it is fun to get the idea of bulk down.
Option #2 is that you could use filter patch bags and wait for the jars to fully colonize...then wait 5 more days for the centers to complete. Then place your bulk sub in the bags, then pasteurize at 160 degrees for atleast 1 1/2 hour to make sure the center is done. Mix wth coir and verm and you will have a real nice and porous sub. Then just seal the bags and wait till harvest. easier than tubs and less space needed. one cake per bag. seal the bage and break up the cake with your hands from the outside once the bag is sealed. That way you do not come in contact with the cake or sub.

well my bags are already pasteurized u think ill yield as much with the bags ? does surface area matter? i would think id get a bigger yield but fewer flushes with tubs. ill try 1 bag like that lik i said i 4 bags and makin 2 monotub 1 bag each tub. every other cakes shotgun
